Well Completion Oscillation Screw

INTRODUCTION

It gently oscillates the Bottom Hole Assembly to improve weight transfer and reduce friction while drilling horizontal wells.
This tool has provided unparalleled downhole friction reduction technology for far longer than any other tool in the industry. The Agitator gently oscillates the Bottom Hole Assembly to significantly improve weight transfer and reduce friction. This improves weight transfer and reduces stick-slip in all modes of drilling, but especially when oriented drilling with a steerable motor.
The Agitator oscillation tool provides BHA excitement to improve weight transfer to the bit. Extends the boundaries of extended reach drilling with motors, or enhance efficiency in less complex or rotary applications.

FEATURES$BENEFITS
1. Significantly Improves Directional Control
• Gentle oscillation of BHA reduces friction and dramatically improves weight transfer
• Enhances toolface control & reduces Stick-slip
• Extends step-out capability
• Prevents weight stacking and allows excellent tool face control
• Provides means of sliding at increased ROP and lower weight off hook
• Allows weight transfer with less drill pipe compression
2. Bit Friendly
• Can be used with roller cone bit or fixed cutter bits
• No impact forces to damage teeth or bearings
• Extends PDC life through fine weight transfer; no spudding
3. Downhole Tool Compatibility
• Fully compatible with all vendor MWD/LWD
• Field proven above RSS
• Reduces shocks during drilling
• Reduced lateral and torsional vibration
• Optimized steerable assembly rotary efficiency
• No interference with downhole tool signals
• Run above or below MWD
• No impact force to bit or tubulars
